freecia, thanks for those links.
I stumbled upon a JR West site which works in very similar fashion to Hyperdia. The site worked for all of my test itineraries between Tokyo and stations to the west and on the routes for the Hokuriku and Joetsu Shinkansen. However, it did not work for any routes between Tokyo and any stations along the Tohoku Shikansen route. So, I'll use the JR West site along with the jorudan site for future JR trips.

We've been fortunate to have had access to the free Hyperdia site for many years. It would be worth paying for a one/two month subscription just prior to a trip-Hyperdia had been a great planning tool.
